EYELETING MACHINE.

Original application filed December 1, 1926, Serial No.1'151e13\nivmed and this January 20, 1928.

This invention relates to improvemei'its in eyeleting machines employed for setting eyelets in shoe-uppersand other articles with which eyelets are used. 1

The object of the present invention is to provide means in duplex machines ofthis character for laterally displacing or [dis charging the punchings from the punclrspin guiding them to a suitable point of deposit.

In machines of this type now in general use punching mechanism and eyelet-setting 1nech anism are arranged in top and bottom sets,

. above and belowa common anvil, and both sidesof the upper are eyeleted at the same time, eyelet. holes being simultaneously punched in them and then eyelets arepositioned and affixed in place in the holes. The

punching and setting mechanisms with their common anvil are mounted on a. movable head, and each punch and setting-plunger is operated by its own hammer; the punches to out eyelet-holes in both sides of the shoeupper, the set-mechanism to pick up eyelets and position them in the holes in the shoeupper and toaflix them therein, and'then the punches to cut the next pair of eyelet-holes. The die or punch spindles are hollow and open. at their outer ends, and the punchings are crowded through the spindles by the pres sure of succeeding punchings and pass out of the openends. As the hammers for the eyelet-settin g devices are directly over and cover the open ends of the punch-spindles they prevent the use of a conduit to receive and convey the punchings away.

By our invention the punchings are positively displaced and discharged laterally from the punch-spindles, so that their egress is uniform and steady and a conduit can be used to guide them from the machine to any place of deposit.

7 Our invention consists in the organizations and arrangen'ients of parts hereinafter described and claimed, and a practical embodiment thereof is shown in the accompanying drawings in whichFig. 1 is a view in front elevation of part of a duplex-set machine equipped with our invention; Fig. 2 isa view of parts of the same in side elevation takenon the punchings discharge side; Fig. 3 is a similar view taken on the opposite side; Figs. 4'

and 6 are detail sectional views taken on the correspondingly numbered lines in Fig. 1, and

I application Serial No. 248,962. p

In the drawings we show a punchand set head of a well-.known type of duplex-set eyeleting machine comprising azbody portion ,1, upper and lower forwardlyprmecting arins2 and 3 each having a vertically elongatedbearing-block,and an anvil 5 fixed at its inner end on the head with its free end intermediate the blocks4 and provided on its upper and lower faces with an inner punch-hlockfiand an outer eyelet setting die 7 Each bearingblock 4 is provided withjinner and outer vertical guide/ways 8 and9, respectively, the former beingin axial alinement withthe punclvhlocks. (Stand the'latter withthe setdies 7. Reciprocating tubular punch-spindles 10 arelocated in the guideways 8 and are providedat their inner or facing ends with hollow cutting punches 11 to co-operate with the punch-blocks 6' to cut holes in the shoe-upper, and at their outer ends with laterally extended lugs 12 which run in guide-slots 13 in the same sides of the blocks 4; they are normally held in retracted position away from the anvil by spring-stressed levers 14 mounted on the machine and engaging cross-slots 15 in the lugs 12, and are projected for their cutting strokes by hammers 16 pivoted on the machine and suitably actuated to engage the lugs 12.. Reciprocating set-sleeves 17 are located in the guideways 9 and are provided at their outer ends with laterally extendedlugs 18' which run in guide-slots 19 in the same sides of the blocks 4. Each sleeve 17 is provided with a spring-pressed set-spindle 20 which picks up the eyelets from a feed-device and delivers them to the set-dies 7; the inner ends of the sleevesare formed to co-act with the dies 7 to afiix the eyelets in the holes in the material, and each sleeve is operated for its setting stroke by a hammer 21 and is retracted by a spring-stressed lever 22 which engages its lug .18. The hammers 21 are pivo-tally displacing the punchings from the punchspindles and discharging them through the bearing'blocks. Each punch spindle. 10 is provided on its side opposite its ,Q llldeil lilg with an axially-elongated and; iateraily di rected discharge orifice 23, 111d the outer end away from its punch 11 to form a lateral] guide to deflect the punchlngs out of the of its bore is closed as b, a Jlu 24; and the y l a closure has a beveled or inclined inner wall 25 extending transversely of the bore at the outer end of its orifice 23 and in a direction spindle through its orificeflEach" bearingblock i is provided with a lateral passage 26 which registers with the orifice 23 when the spindle 1O isin its retractcdpositi'on and duringthe movement the spiiidle toward its punch-block and hile the cut-tingoperation occurs,and the lugsm and guide-slots 13 ensure their Vertical ahneme'nt. Eachfpisstead of from L the] en ds o'f the spindles: By this orgenlzation" punchings-d sposal vcoir duit-s are arranged out of the Way of the sch hammers or other necessaiiy parts of the machine and the objection to discharging the punchings out of the ends of the. spindles is obviated. Also, the disposal devices are attached to the bearing-blocks and so are pcrv menen'tly mounted on-the head.
